Motor Protection Electronics offers three level controllers that are Modbus SCADA-ready. The Duplexer Controller is for controlling two pumps using floats or a conductance level probe for its inputs. The SC1000 Controller controls from one to three pumps using either a 4-20mA analog signal or a conductance level probe. The SC2000 Controller controls from one to four pumps, either constant speed or variable speed. The SC2000 also accepts inputs as either a 4-20 analog signal, or inputs from a conductance level probe. Motor Protection Electronics also manufactures Phase Monitors, Alternators, Time Delay Relays, Conductance Level Probes, Bubbler Systems, and Intrinsically Safe Relays, Controllers and Barriers.See list of news items about this company...

The M.P.E. DUPLEXER is a low cost Modbus SCADA-ready pump controller designed to perform level control for duplex lift station applications. The level inputs can be connected to either four float switches or to a conductance probe. The Duplexer provides a 10-second power-up start delay, 5-second lag pump delay, and duplex alternation. LEDs provide power on status, level input status, pump call status, and high level alarm status indication. Pump 1&2 call and high level alarm relays are provided. HOA and lead select toggle switches are also provided. The high level status indication latches upon high level, until reset by pressing the reset push-button (the relay does not stay latched). Level simulation is accomplished by pressing and holding the push-button. Releasing the push-button allows the simulated level to return to normal. Connecting the serial port to a SCADA system allows the lift station to be monitored and controlled remotely. By connecting a programming device to the serial port (MPE p/n TSID), a number of settings may be accessed to customize the unit.

The M.P.E. SC1000 is a Modbus SCADA-ready pump controller designed to perform level control in a wide range of lift station applications. The SC1000 operates the pumps based on the selected setup values and the wet well level signal. The level input source is menu selectable for either a 4-20 mA pressure transducer, or a 10 point conductance probe. The SC1000 alternates the pumps, performs lag pump delays, and provides high and low level alarms. The SC1000 has a variety of control options available in the setup menu that may be used to customize the controller for a specific application.
